# Clip 3/14: Introduction - Part A

## Overview

Fran starts the lesson reminding the learners of the work they have been doing leading up to today.

In the number talk "guess my rule," as the learners guess input numbers, the educator generates the output number. After each guess Fran has one of the learners “graph the point.”

## Teacher Commentary

We had done two previous number talks involving “guess my rule?” The difference in today’s number talk was the graphing of the coordinate values.

In our planning, we decided to set parameters for the learner guesses to keep all of the points in the first quadrant. We had only recently begun investigating coordinate pairs and we thought it would simplify things to have the learners focus.
